Description:
Arrays of dual-frequency GPS receivers operating in the Arctic and
Antarctic monitor scintillation and ionospheric total electron content
at high latitudes. Even under solar minimum conditions, events of
significant phase scintillation have been observed in both polar caps.
Climatology studies in both hemispheres show that phase scintillation
as a function of magnetic local time and geomagnetic latitude
primarily occurs in the nightside auroral oval and ionospheric cusp,
with the scintillation regions shifting in latitude in response to
varying geomagnetic activity. Preliminary results from the first
comparative scintillation study supported by ground-based
instruments including HF radars, ionosondes and all-sky imagers are
presented. In the future, in-situ measurements by the Enhanced Polar
Outflow Probe (ePOP) will provide additional support to study the
Arctic and Antarctic ionospheres.
